Abstract
ALMENDRAL DONCEL, R. and PEINADO POSTIGO, F.. Prevalence and type of electroencephalographic alterations in attention deficit hyperactivity disorder. Rev Pediatr Aten Primaria [online]. 2014, vol.16, n.64, pp.e133-e138. ISSN 1139-7632. https://dx.doi.org/10.4321/S1139-76322014000500003.
Introduction: the prevalence and clinical significance of alterations electroencephalographic (EEG) in patients with attention deficit disorder with hyperactivity (ADHD) has not been elucidated. Objectives: estimate in pediatric patients diagnosed with ADHD and no history of seizures the prevalence and type of EEG abnormalities. Patients and methods: we selected during 2010 all patients with ADHD seen in a reference Neuropediatric Unit. In all cases an EEG was performed with partial sleep deprivation up to 5 hours and a duration record of 30 minutes by the International System (10/20). We estimated the prevalence and confidence interval of 95% (CI 95%) with the exact method. Results: we recruited a total of 62 cases, 45 boys (74.2%) y 6 girls (25.8%) with a mean age of 9.2 years (SD 2.6 years, range 6-14 years). Most were ADHD combined type (54.8%), followed by the type attention deficit (33.9%) and hyperactivity (11.3%).Only one case was detected with EEG abnormalities (prevalence 1.6%, CI 95%: 0.04 to 8.7%). It was a male, 7 years old, combined ADHD subtype in which there was a left temporal spike-wave center. Conclusions: the prevalence of abnormal EEG in patients with ADHD is low in our environment, similar to that expected in the general population.
